First responders in San Francisco are dealing with two separate traffic incidents that happened around the same time Monday afternoon, one of which sent a bicyclist away in an ambulance after colliding with a car.

Earth and the Sun may be 93 million miles apart, but cosmic explosions between the two celestial spheres occur often and with devastating effects–unleashing waves of radiation and disrupting GPS communications, and it is with this danger in mind that next month, NASA will launch four “Magnetospheric Multiscale Mission” satellites, studying these “magnetic reconnections” and better predicting the consequences of these cosmic phenomena.

The four-alarm fire that devastated a three-story building in San Francisco’s Mission District has had a big impact on dozens of small businesses. Among those hit hard, is one of city’s best known delis.
